In an email to city officials making the rounds, APD Lieutenant Bart Silvers offers a postmortem of last night’s festivities on the Plaza:

Halloween saw a couple thousand people in the downtown area once again. We deployed with allied agencies in the same fashion as New Years Eve 2012. There were a total of 36 sworn officers, approximately 15 Academy cadets and and additonal 6 volunteer and non sworn members of APD. While we were successful in keeping the Plaza from being destroyed, the crowd once again turned violent.

While arresting a female subject who had been involved in a physical fight, officers became surrounded by the crowd. The crowd began to throw objects at the officers and an APD sergeant was struck in the face with a bottle. He sustained a large laceration to his upper lip and had to be transported to Mad River Hospital where he received several stitches. The crowd continued to be unruly and several more arrests were made throughout the night.

During the evening officers located a male subject with an AR-15 assault rifle slung around his neck. The firearm had an unusable unloaded magazine in the weapon. He also had a loaded operable 10 round magazine in his pocket. The weapon was taken for public safety reasons.

The operation resulted in 9-647(f) arrests, numerous medical aid calls which consisted of a broken nose, broken jaw (which were sustined during physical altercations in the downtown area) and other alcohol related issues.
